twalthr opened a new pull request #16536:
URL: https://github.com/apache/flink/pull/16536
## What is the purpose of the change
This refactors some enum classes that are used for more or less the same
purpose but in different parts of the stack with different values. It should
reduce confusion and collisions with API classes.
The new naming is as follows:
```
DataExchangeMode (for network stack, remains as it is)
ShuffleMode -> StreamExchangeMode (belongs to *stream* graph and influences
the data *exchange*)
GlobalDataExchangeMode -> GlobalStreamExchangeMode (belongs to *stream*
graph and influences the data *exchange* but globally)
```
In docs and API we expose the word "shuffle" also for shuffle service etc.,
thus, we will add a new `ShuffleMode` enum according to FLIP-134. The enum
class will follow in the next PR. The word "exchange" is used internally for
declaring shuffles in graphs.
## Brief change log
Use the term "exchange mode" consistently.
## Verifying this change
This change is a trivial rework / code cleanup without any test coverage.
